ABSTRACT
Communication to and between road vehicles are of growing interest. This is partly due to the attractive services that cooperative intelligent transport systems (C-ITSs) provides, mainly in the areas of traffic safety and traffic efficiency. An enabler for C-ITS is wireless vehicle-to-vehicle and vehicle-to-infrastructure communication, collectively referred to as vehicle-to-X (V2X) communication. Another driver is the advent of moving networks in the context of 5th generation (5G) systems. This chapter discusses key issues in V2X communication: propagation, antennas, and physical and medium access control layer algorithms. Vehicular connectivity will be rolled out via several radio access technologies; Third generation/Fourth generation long-term evolution, wireless local area network, Bluetooth, 802.11p, and possibly 5G in the future. In traditional channel modelling, the wide-sense stationary-uncorrelated scattering assumption has been widely used to describe random linear time-varying cellular channels.
